(4.2) Duplicates
If one of your unique cards is about to leave play, as a triggered ‘Response:’ effect, you may discard an attached duplicate to save the unique card from leaving play… Using a duplicate to save a character is considered to be a gained triggered "Response:" action. Thus, it is treated as a triggered effect and may be canceled, but because it is gained (and therefore
an ability of the card attempting to use the response
), a character who is "immune to triggered effects" can be saved by using a duplicate, as a card cannot be immune to its own abilities.
I'm wondering if this is a character ability or simply a triggered effect that the player gains when his duped card would leave play, as the wording seems a little odd (though it sounds to me like it is a gained character ability) The reason I looked into this is that the plot Burning Bridges , which I have in one of my decks, would prevent players from using duplicates to save their characters if the former were true.
